Description

[Detailed Description of the Invention] [Industrial Application Field] The invention of this application relates to an upper end attachment of a shoulder belt for backpacks such as school bags and backpacks.

[Conventional technology]

Conventionally, the upper end attachment of the shoulder belt of this type of backpack has been attached to the top of the backrest or at a position slightly lower than the top. In most cases, this shoulder belt upper end mount is fixed at that position, so the mounting position of the shoulder belt cannot be moved. As shown in No. 63-49455, a school bag equipped with a shoulder belt upper end fixture that can move the shoulder belt attachment position in the vertical direction has been devised.

[The problem that the idea attempts to solve]

The shoulder belt upper end mount shown in the above-mentioned Utility Model Application No. 63-49455 is easy to use because the mounting position of the shoulder belt can be moved up and down according to the user's physique. However, the mounting position of the shoulder belt cannot be moved in the left-right direction, and the ease of use is still insufficient, and improvements in this respect have been desired.

Therefore, the invention of this application allows the mounting position of the shoulder belt to be moved in the vertical direction as well as in the horizontal direction, so that it can be perfectly matched to the user's physique. The purpose of the present invention is to provide an upper end attachment for a shoulder strap for a backpack.

[Means to solve the problem]

Therefore, the upper end attachment device for the shoulder belt of the backpack invented in this application is designed so that the connection plates 4, 4, to which the left and right pair of attachment rings 3, 3 are attached, can be slid in an abbreviated shape and are sandwiched so that they can be positioned at appropriate positions. The upper and lower covering plates 5a and 5b are attached to the backrest part 7.

[Effect]

The invention of this application has the following effects because it has the above-mentioned means.

That is, the connecting plates 4, 4 to which the mounting rings 3, 3 are attached slide in an abbreviated shape, and the mounting rings 3, 3 move diagonally upward, thereby moving the mounting position of the shoulder belt in the vertical direction. It can also move left and right.

〔Example〕

Hereinafter, the configuration of the shoulder strap upper end attachment for a backpack according to the invention of this application will be explained based on the drawings showing an embodiment thereof.

FIG. 1 shows a perspective view of a school bag equipped with the shoulder belt upper end attachment of this invention, viewed from the back rest side. Reference numeral 1 denotes a shoulder belt. The upper end of the shoulder belt 1 is attached to an upper end fixture 2, and the lower end of the shoulder belt 1 is attached to a lower end fixture (not shown).

The upper end fitting 2 has a pair of left and right mounting rings 3, 3.
The upper and lower covering plates 5a and 5b sandwich the connecting plates 4 and 4 attached thereto so that they can be slid in an abbreviated shape and positioned at appropriate positions, and are attached to the back rest part 7 of the school bag 6.

In the embodiment, in order to enable the connecting plates 4, 4 to slide in an abbreviated shape, sliding grooves 8, 8 arranged in an abbreviated shape are formed in the lower cover plate 5b, and these sliding grooves 8, 8 are The connecting plates 4, 4 are inserted respectively. In addition, in order to position the connecting plates 4, 4 at appropriate positions, screw holes 10, 1 are provided in the lower cover plate 5b from through holes 9, 9 provided in the upper cover plate 5a.
0, screws 12, 12 are inserted through any one of several stages of through holes 11 provided in the connecting plates 4, 4, respectively.

Rivet holes 13a..., 13b... are provided at the peripheral ends of the upper and lower cover plates 5a, 5b, and rivets 14... are passed through these rivet holes 13a..., 13b... to attach the upper and lower cover plates 5a, 5b to the school bag. It is attached to the backrest part 7 of 6 by riveting. Furthermore, ribs 4a are formed on the connecting plates 4, 4 for reinforcement.

Note that 15 is a name card holder provided on the upper and lower cover plates 5a. Furthermore, 16 is a hanging ring for hanging the school bag when not in use, and is attached to the connecting body 17. This connecting body 17
is sandwiched between the upper and lower covering plates 5a and 5b, and is pivotally supported by the back rest part 7 of the school bag 6 together with the upper and lower covering plates 5a and 5b.

[Effect of idea]

The shoulder strap upper end attachment for a backpack according to the present invention is constructed as described above, and therefore has the following effects.

That is, the connecting plates 4, 4 to which the attachment rings 3, 3 are attached slide in an abbreviated shape, and the attachment rings 3, 3 move obliquely upward, thereby tightening the shoulder belt 1.
Since the mounting position of the device can be moved vertically as well as horizontally, it is extremely easy to use and does not give the user a feeling of pressure or fatigue.
